C. A. PFEIFER Feb. 9, 1954 TIRE RIVET Filed March 4, 1950 Zhwentor 1. #9. pF Fe- W mum Gttorneg Patented Feb. 9, 1954 UNITED STATES PATENT OFFICE Another object of the invention is to provide a device of the type having a wire leader and cord link which will be effectual for insertion of the rivet through a puncture hole in the tire and will at the same time be releasable during the operation for reuse of the leader and cord.

Other and further objects of the invention will appear as the description proceeds, reference bein had to the accompanying drawing, in which:

Fig. 1 is a View in perspective of a tire rivet embodying the invention.

Fig. 2 is a sectional view taken transversely through a tire showing three steps in the application of one of the rivets.

Referring more particularly to the drawing, the numeral l0 represents a twisted wire leader having the insertion point H and the eye formation l2 at its blunt end. The tire rivet I 3 is comprised of a circular base portion I4 and an elongated stem having a reduced portion at I6 thereof. The base portion 14 is thickest in its central part and is graduated toward the edge thereof to relative thinness. The rivet I3 is preferably formed of rubber or other resilient material having sulficient elasticity for the purpose.

A cord link 11 connects the wire leader I!) with the rivet l3 and has a knot at I 8 thereof. The cord I7 is looped at l9 through the eye I2 of the Wire leader l0, and is double looped at about the reduced portion I6 of the rivet 13. The cord 1 may be formed of any suitable material but adapted for the purpose.

In use, a tire casing 2| which has been punctured as at 22 may be repaired by coating the stem 15 of the rivet I3 and its reduced portion 6 with a quantity of rubber cement, after which the wire leader I0 is introduced by its pointed end from the inside of tire casing 2| through the inside 24 of said tire casing surrounding the puncture 22. If this action is taken with the right amount of force, the cord I! will pull the stem I5 a sufficient distance through the puncture opening 22 and will then release the reduced portion 16 so that the leader I!) and the cord 11 may be used repeatedly with other rivets l3. The stem 15 and its reduced portion IE will then prothe casing 2| to make a good repair.

It will be understood that the device is capable claimed and desired to be secured by Letters Patent of the United States, is:

In combination, a twisted wire leader having an eye on one end thereof, a resilient tire rivet, a circular base on said rivet, a stem integral there- CARL A. PFEIFER.
